02.50: Two thin lenses each with a focal length of +10 cm are located 30 cm apart with their optical axes aligned as shown. An object is placed 35 cm from the first lens. After the light has passed through both lenses, at what distance from the second lens will the final image be formed?

  05.41: In a system of lenses, it is reported that when tsogx6fa / qas*2t5ja5he calculation of the magnification was performed on a diverging lens that has focal length of magnitude f, the image saqo2xa jss5/5a gft*6 ize was identical to that of the object. How is this possible?

  07.43: Which of the following best re a us (1x7,gj 68by.p btfqc)evd8)fpgpresents the ray diagram construction for finding the image formed for8u efx8s,d7(y gvt6c1jbp.fqga b )p) the virtual object shown? The solid dots on either side of the lens locate the equal magnitude foci of the lens.

  15.34: An upward-pointp2/0kyd jfi 9+.qycva ing object is placed 15.0 cm to the left of a lens system. The first lens is convex with focal length 10.0 cm. The second lens is convex with focal length 10 c???? and its location from the first lens is varied from 10 cm away to 110 cm away. Which one of the following choices best represents the description of the final image formed as the second lens is moved from x = 10 cma kf9qv/ .dp20yc+yji to x = 110 cm from the first lens?
